In the past decade, study abroad programs (SAPs) have more than doubled, where today, about 223,000 U.S. college students study abroad, immersing themselves in foreign language, culture, and business practices. It is customary to hear students describe these experiences as "life changing," yet little empirical evidence exists to establish the specific areas of personal development achieved in a SAP. This study investigates several of the potential intercultural influences of a semester abroad for students from the United States. Findings reveal that students who study abroad may have greater intercultural proficiency, increased openness to cultural diversity, and become more globally minded than those students remaining in a traditional campus setting. Students who participate in SAPs perceive themselves as being more proficient, approachable, and open to intercultural communication. (Contains 1 table.)
